docs: def refreshGroupMembership(self, groups):
          """
          This operation iterates over every enterprise account configured in
          the portal and determines if the user account is a part of the
          input enterprise group. If there are any change in memberships, the
          database and the indexes are updated for each group.
          While portal automatically refreshes the memberships during a user
          login and during a periodic refresh configured through the Update
          Identity Store operation, this operation allows an administrator to
          force a refresh.

             groups - comma seperated list of group names
